The index is exposed just as 'index' in the delegate itself.

I think Component.onCompleted is run any time something creates the
component, which might not be what you want if you're using the same
delegate for multiple views. The exact point at which ListView.onAdd
is called might also vary and that might be important if you're using
transition animations when modifying the ListView elements.

There are some other ways you can do it too -- using the
'onCountChanged' handler in the ListView, etc.
